Is there such an animal as a corner rounder for metals? Something
that could handle at least an 062 5052 aluminum?
I have a lot of bench equipment but I've never seen a rounder.
Roper, Diacro, etc?

If you're asking an honest question:
Just what, specifically, are you referring to as a "corner rounder for
metals" and what do you want to do with it?
Are you looking for the equivalent of a woodworking router with a carbide
roundover bit to "ease" the edges of heavy Al plate? If so, that's your
answer.
Are you looking for a simple way to dull sharp corners? That can be done in
a variety of ways ranging from hand tools to power tools depending upon the
job and the number of pieces to be processed.
OTOH, if you're just looking for a way to knock off the corners of a piece
of thin sheet, most any abrasive wheel - from a Dremel sanding drum to an
angle grinder & flap wheel to a disk or belt sander to a bench grinder -
can do the job if you're unwilling to use a file.

If you mean rounding off a long edge, there are several ways to do
it. Corner rounding (quarter circle or half circle) milling cutters
(shanked or arbor mounted) used in a milling machine are one common
way. There are some single-purpose machines with similar cutters and
90 degree beds, if you're doing a lot of pieces. As someone
mentioned, a router with a woodcutting bit will work on aluminum.
If you mean rounding over a corner on a thin flat piece, those same
methods may not work. Unless you gang a bunch of thin pieces
together, or otherwise support them, they may not be stiff enough to
resist a milling cutter. A file is often easier. There are ways to
machine it, though.

Please log in for more thread options I believe that there is- Roper Whitney makes a tool, which I have
wanted for years, called a Radius Master.
It is a corner rounder for sheet metal.
http://www.braunerequipment.com/f_prod_detail.aspx?id=190
It has different radius dies, so the one machine can do everything
from 1/8" to 1" radiused corners, with up to 3" dies available on
special order.
It is hideously expensive- which is one reason you probably have never
seen one.
I have never seen one used, and I doubt they sold very many new.
I believe they are close to 5 grand new, now.

Starts at $6400 bucks. Great price if you're going to be using it
every day!
